Hundreds of scientists packed an auditorium at one of the world's foremost laboratories on the Swiss-French border to hear how a subatomic particle, the neutrino, was found to have outrun light and confounded the theories of Albert Einstein.

Going faster than light is something that is just not supposed to happen, according to Einstein's 1905 special theory of relativity. The speed of light — 186,282 miles per second (299,792 kilometers per second) — has long been considered a cosmic speed limit.

Actually fluoride is a natural mineral that, in the weak concentrations used in public drinking water systems, hardens tooth enamel and prevents tooth decay—a cheap and safe way to improve dental health for everyone, rich or poor, conscientious brusher or not. That’s the scientific and medical consensus.

when Galileo claimed that the Earth spins on its axis and orbits the sun, he wasn’t just rejecting church doctrine. He was asking people to believe something that defied common sense

all manner of scientific knowledge—from the safety of fluoride and vaccines to the reality of climate change—faces organized and often furious opposition.

I talked to a half-dozen of Hugh Moren’s fellow students. A highly indebted senior who was terrified of the weak job market described George Washington, where he had invested considerable time getting and doing internships, as “the world’s most expensive trade school.” Another mentioned the abundance of rich students whose parents were giving them a fancy-sounding diploma the way they might a new car. There are serious students here, he acknowledged, but: “You can go to G.W. and essentially buy a degree.”

A recent study from the Organization for Economic Cooperation and Development found that, on average, American college graduates score well below college graduates from most other industrialized countries in mathematics. In literacy (“understanding, evaluating, using and engaging with written text”), scores are just average. This comes on the heels of Richard Arum and Josipa Roksa’s “Academically Adrift,” a study that found “limited or no learning” among many college students.Instead of focusing on undergraduate learning, nu

colleges have been engaged in the kind of building spree I saw at George Washington. Recreation centers with world-class workout facilities and lazy rivers rise out of construction pits even as students and parents are handed staggeringly large tuition bills. Colleges compete to hire famous professors even as undergraduates wander through academic programs that often lack rigor or coherence. Campuses vie to become the next Harvard — or at least the next George Washington — while ignoring the growing cost and suspect quality of undergraduate education.

More 5inShare Email Print A defendant in the Atlanta Public Schools case turns herself in at the Fulton County Jail on April 2. (David Goldman/AP) Earlier this week at The Atlantic, Emily Richmond asked whether high-stakes testing caused the Atlanta schools cheating scandal. The answer, I would argue, is yes... just not in the way you might think. Tests don't cause unethical behavior. But they did cause the Atlanta cheating scandal, and they are doing damage to the teaching profession. The argument that tests do not cause unethical behavior is fairly straightforward, and has been articulated by a number of writers. Jonathan Chait quite correctly points out that unethical behavior occurs in virtually all professions -- and that it occurs particularly when there are clear incentives to succeed. Incentivizing any field increases the impetus to cheat. Suppose journalism worked the way teaching traditionally had. You get hired at a newspaper, and your advancement and pay are dictated almost entirely by your years on the job, with almost no chance of either becoming a star or of getting fired for incompetence. Then imagine journalists changed that and instituted the current system, where you can get really successful if your bosses like you or be fired if they don't. You could look around and see scandal after scandal -- phone hacking! Jayson Blair! NBC's exploding truck! Janet Cooke! Stephen Glass! -- that could plausibly be attributed to this frightening new world in which journalists had an incentive to cheat in order to get ahead. It holds true of any field. If Major League Baseball instituted tenure, and maybe used tee-ball rules where you can't keep score and everybody gets a chance to hit, it could stamp out steroid use. Students have been cheating on tests forever -- massive, systematic cheating, you could say. Why? Because they have an incentive to do well. Give teachers and administrators an incentive for their students to do well, and more of them will cheat. For Chait, then, teaching has just been made more like journalism or baseball; it has gone from an incentiveless occupation to one with incentives.

Chait refers to violations of journalistic ethics -- like the phone-hacking scandal -- and suggests they are analogous to Major-League steroid use, and that both are similar to teachers (or students) cheating on tests. But is phone hacking "cheating"

Phone hacking was, then, not an example of cheating. It was a violation of professional ethics. And those ethics are not arbitrarily imposed, but are intrinsic to the practice of journalism as a profession committed to public service and to truth.

Piper, Mijares and their team published a description of the foot bone in 2010. They knew it was the oldest human remain in the Philippines, dated to 67,000 years ago, based on the amount of the radioactive element uranium in the fossil

Mijares returned to Callao Cave and uncovered more remains in 2011 and 2015. All told, the scientists pulled a dozen fossilized parts from the cave — teeth, a thigh bone, finger bones and foot bones, representing three individuals. Attempts to extract DNA from the remains were unsuccessful.

The body parts are diminutive, suggesting Homo luzonensis grew no more than four feet tall. Its molars have modern shapes. The way its leg muscle attached to its thigh bone is “distinctively human,”

Soya’s fame illustrated a simple truth: that social media is less a reflection of who we are, and more a performance of who we want to be.

It also seemed to herald a darker future where our fundamental senses of reality are under siege: The AI that allows anyone to fabricate a face can also be used to harass women with “deepfake” pornography, invent fraudulent LinkedIn personas and digitally impersonate political enemies.

As the photos began receiving hundreds of likes, Soya’s personality and style began to come through. She was relentlessly upbeat. She never sneered or bickered or trolled. She explored small towns, savored scenic vistas, celebrated roadside restaurants’ simple meals.

Uganda's President Yoweri Museveni has won a sixth term in office, fighting off a challenge by former singer Bobi Wine

Wine's run drew many young Ugandans to pay attention to politics.

Museveni received 58% of the vote to 34% for Wine

A RELATIVELY new field, called interpersonal neurobiology, draws its vigor from one of the great discoveries of our era: that the brain is constantly rewiring itself based on daily life.

All relationships change the brain — but most important are the intimate bonds that foster or fail us, altering the delicate circuits that shape memories, emotions and that ultimate souvenir, the self

At birth, the brain starts blazing new neural pathways based on its odyssey in an alien world. An infant is steeped in bright, buzzing, bristling sensations, raw emotions and the curious feelings they unleash, weird objects, a flux of faces, shadowy images and dreams

The question is not how languages gradually developed over time into the languages of the world today. Rather, it is how the human species developed over time so that we - and not our closest relatives, the chimpanzees and bonobos - became capable of using language.

Human language can express thoughts on an unlimited number of topics (the weather, the war, the past, the future, mathematics, gossip, fairy tales, how to fix the sink...). It can be used not just to convey information, but to solicit information (questions) and to give orders.

Every human language has a vocabulary of tens of thousands of words, built up from several dozen speech sounds

The cognitive benefits of bilingualism can begin from experiences very early in childhood and can persist throughout life.

The first main advantage involves what’s loosely referred to as executive function. This describes skills that allow you to control, direct and manage your attention, as well as your ability to plan

The brain is made up of cells called neurons, which each have a cell body and little branching connections called dendrites.

The researchers found that reasons for believing in conspiracy theories can be grouped into three categories: The desire for understanding and certainty The desire for control and security The desire to maintain a positive self-image

Seeking explanations for events is a natural human desire

We all harbor false beliefs, that is, things we believe to be true but in fact are not.

A paper posted online last month has reignited a debate about one of the oldest, most startling claims in the modern era of network science: the proposition that most complex networks in the real world—from the World Wide Web to interacting proteins in a cell—are “scale-free.” Roughly speaking, that means that a few of their nodes should have many more connections than others, following a mathematical formula called a power law, so that there’s no one scale that characterizes the network.

Purely random networks do not obey power laws, so when the early proponents of the scale-free paradigm started seeing power laws in real-world networks in the late 1990s, they viewed them as evidence of a universal organizing principle underlying the formation of these diverse networks. The architecture of scale-freeness, researchers argued, could provide insight into fundamental questions such as how likely a virus is to cause an epidemic, or how easily hackers can disable a network.

Amazingly simple and far-reaching natural laws govern the structure and evolution of all the complex networks that surround us,” wrote Barabási (who is now at Northeastern University in Boston) in Linked. He later added: “Uncovering and explaining these laws has been a fascinating roller-coaster ride during which we have learned more about our complex, interconnected world than was known in the last hundred years.”

Many animals store food to use in times of scarcity, but humans are stockpilers too — individuals routinely keep money in the bank (or under their mattress) and cans in the pantry. However, in some individuals, this collecting behavior is taken to extremes in the form of compulsive hoarding — collecting excessive amounts of objects that have little or no value. Preston found that, across species, including humans, anxiety and threats appear to increase the motivation to acquire and collect food and goods

Responses to positive and negative feedback in the ventral striatum were greatly reduced under stress as compared to when there was no stress, suggesting that stress may dampen your perception of the subjective value of a decision.

Gaining a better understanding of how stress affects decision making is critical not only for psychological science, but has important, real-world implications

Facebook, which has faced heavy criticism for its lack of transparency on political ads, welcomed the move.

“We have long called for EU-wide regulation on political ads and are pleased that the Commission’s proposal addresses some of the more difficult questions, in particular when it comes to cross border advertising,” the company, which recently renamed itself Meta, said in a press statement.

Google said in a blog post that it supported the proposals and recommended the commission clearly define political ads and spell out responsibilities for tech platforms and advertisers while still keeping the rules flexible.

“We’re used to thinking that information about an object — say that a glass is half full — is somehow contained within the object.” Instead, he says, entanglement means objects “only exist in relation to other objects, and moreover these relationships are encoded in a wave function that stands outside the tangible physical universe.”

Einstein, though one of the founders of quantum theory, rejected it, saying famously, God did not play dice with the universe.In a 1935 paper written with Boris Podolsky and Nathan Rosen, he tried to demolish quantum mechanics as an incomplete theory by pointing out that by quantum rules, measuring a particle in one place could instantly affect measurements of the other particle, even if it was millions of miles away.

Dr. Clauser, who has a knack for electronics and experimentation and misgivings about quantum theory, was the first to perform Bell’s proposed experiment. He happened upon Dr. Bell’s paper while a graduate student at Columbia University and recognized it as something he could do.

When we are herding, neuroimaging experiments show increased activation in the amygdala area of the brain, where fear and other negative emotions are processed. While you may feel vulnerable and exposed on your own, being part of the herd gives you a distinct sense of protection. You know in your guts that, in the midst of others, the risk of being hit by a car is lower because it is somehow distributed among the group’s members

The more of them, the lower the risk. There is safety in numbers. And so much more than mere safety.

Herding also comes with an intoxicating sense of power: as members of a crowd, we feel much stronger and braver than we are in fact.
